The circle at the centre of this pavilion is filled with a thick layer of rock dust, which was ground into a fine grey powder over centuries through the slow movement of glaciers. This so-called glacial rock flour was taken by Eliasson from Greenland and installed originally in the gardens of Versailles, France, as part of the artist’s exhibition there in 2016. The installation is a result of Eliasson’s ongoing dialogue with geologist Minik Rosing, who proposes using glacial rock flour from Greenland to revitalise the depleted soil in tropical and subtropical areas, as it is a rich source of the mineral nutrients that sustain crops and other plants. Here, it stands in contrast to the arid desert sand around it, its cracked surface belying the fecundity within.
